Product Description  
EMI/RFI filtering. Conventional thick film-based EMI/RFI  
filters do not effectively suppress noise at high frequen-  
cies due to the fact that EMI/RFI filters using thick film  
technology have high parasitic inductance which  
becomes the dominant component of the capacitor’s  
impedance past resonance, and therefore significantly  
affects high frequency performance of the filter.  
CAMD’s PRC201/211/221 Tapped Filter is designed to  
suppress EMI/RFI noise on high speed data lines and at  
I/O ports of PCMCIA fax/modem and LAN type cards.  
This integrated thin film resistor-capacitor network is  
housed in a ultra low profile, surface mount package  
suitable for bottom side mounting to the card which  
minimizes space and routing problems and improves  
reliability.  
CAMD’s PRC201/211/221 Tapped Filter is fabricated on  
a silicon substrate using advanced thin film technology.  
These EMI/RFI filters have very low parasitic inductance  
and suppress EMI/RFI noise at low and high frequencies  
to well above 1000 MHz.  
Why thin film EMI/RFI filters? EMI/RFI filters are needed  
to suppress noise at low and high frequencies of the  
signal. Ferrite beads used for EMI/RFI filtering are bulky  
and ineffective at low frequencies and have saturation  
problems at high frequencies. Resistor-capacitor  
networks offer the best technical approach for effective
